Here’s a project that was put on the back burner. So rather than it just lying around let’s post and see if someone else can use it Nordstrand 3B with pots input jack and battery terminal. Price is shipped USPS priority mail. Nordstrand 3B Nordstrand 3B-4b - Best Bass Gear Pots are as follows. Volume p/p (for active/passive if you don't want to use a separate switch) 250K Push/Pull Volume - Best Bass Gear Blend (M/N taper) Noble - Blend Pot - 250K Blend - Best Bass Gear (These are the same brand as above, but are what is known as a "no load" blend. when the this blend is in the true center, both pickups are trully full volume. I highly recommend this blend since you will have the ability to bypass the preamp and go passive. Most of the other makers we deal with already use this type of blend. The other blend has a bit of a volume drop in the center position that isn't as noticable in active mode, but I find it problematic for passive, since there is also a small amout of treble loss.) Mid push/pull (for frequency selection, if you don't want to use a separate switch) Noble - EQ Pot - 50K Push/Pull - Best Bass Gear Stack treble/bass Noble - EQ Pot - 50K Stacked - Best Bass Gear This preamp is brand new! Never installed! Thanks for looking.
